Fig. 3.

Fluorescence decay analysis of monomeric and trimeric PSI complexes in solution being either in open or in closed state. Excitation wavelength was 400 nm. The left-most panels (a, d, g, j) present common compartmental model underlying target analysis, including estimated molecular lifetimes and initial populations of particular compartments; the central panels (b, e, h, k) results of the target analysis (species-associated spectra); the right-most panels (c, f, i, l) results of the global analysis (decay-associated spectra). The uncertainty of molecular lifetimes was estimated at ±0.5 ps
